Wide-mouth sterile container

Specimen Requirement

If fluid, collect in sterile container. If exudate, collect in sterile swab. Send immediately to Lab.

Specimen Storage / Transport

Collect three sputum specimens for acid-fast smears and culture in patients with clinical and chest x-ray findings compatible with tuberculosis.

These three samples should be collected at 8-24 hour intervals and should include at least one first morning specimen. Specimens must be delivered to the laboratory promptly.

Specimens that cannot be processed within one hour of the time of collection will be refrigerated during transport to and storage in the laboratory prior to processing. This will decrease overgrowth with contaminating organisms likely to be present.
